AUTOMATIC CARBURETER FOR EXPLosIvE-Mo'rons.

Patented May 26, 1908.

Application measeptember 3o, 1907. seria; 110.395,205.

Be it known that I, Louis MARIE GA- BRIEL DELAUNAY-BELLEVILLE, citizen of j the French Republic, residing at Paris, department of Seine, in France, havevinvented certain new and useful Improvements Rel lating to Automatic Oarbureters for Explol sion-Motors, of which the' following is a speciiication.

This invention has for its object improvements in the carbureters of explosion motors in which two currents are conducted to the j motor, one being a combustible 4current mixed with a certain quantity of air and the j other a current of a second or additional quantity of air. j

In the novel arrangement, the two curi rents,l one the mixture of primary air and pulverized liquid fuel and the other the sup- I plementary air introduced through the automatic valve, are directed in opposite directions, but instead of penetrating each other mutually, each breaks upon an interposed' diaphragm, formed by two conical surfaces arranged 'base to base, .Where they spread out and are then projected parallel one with theother in a plane at right-angles to the direction of their arrival. In this ar rangement, the unvaporized liquid particles mixed with the primary. air cannot be projected by their inertia against the upper walls of the apparatus but are so to speak crushed against the' guide diaphragm; they are thus more intimately mixed with the air which serves as a vehicle for them, because the mixture with the air, deflected from its originalidirection, is projected through the oriiices of the regulator towards the sockets of the cylinders, at the same time that the supplementaryair is projected in the same direction ,by its encounter with the otherv face of the guide diaphragm. As shown in the drawing, this diaphragm may be incorporated with the rotary cylinder which regulates the 'quantities o'f the gases and is oper- .ated by hand by the driver. The seat of the automatic valve .for the supplementary air tary part, or on the other hand, as shown in the drawing, it may form part of the fixed socket or casing of the apparatus.

The rotary part and the socket or casing in which it is displaced around their` common axis, are provided with ports which are section on the line z-z of Fig.

l uncovered and covered to agreater or less the line .fc-4m of Figs. 2 and 3. Fig. 2 is a vertical section on the line y-y ofjFigs. 1 and 2. Fig. 3 is a lan view of the. valve for the admission o cold air. Flg. 4 is a A is the'constant levelfreservoir.

B is the injector. C the inlet for the primary air. C1 the pulverization chamber.

D is the gas mixing diaphragm. This l' diaphragm is bi-conical or of similar form' and is arranged 'in the axis of. a c vlinder D with which it4 is preferably integral.

E is thebox of the diaphragm D. This box is provided with a jacket E. in which the cylinder D is inclosed in such a manner as .to be capable of rotating. This jacket is provided with ports 1 1, arranged 'opposite ports 2--2 in the cylinder D which mutually uncover and cover each other more or less on the actuation of an operating part by the driver. y

F is the valve for the'in'troduction of cold air, establishing communication between the atmosphere andthe box E. This valve' is loaded by a spring 3 it opens under the iniluence of the vacuum,

G-G are conduits leading tov the'cylinders. The right hand conduit and the left hand conduit communicate with each otherv through the Cpassages 4, 4 formed between the box E an its jacket E.

y, g, g, g are ipes proceeding from the conduits G, G and) terminating at the admission valves of the motor cylinders. j

The amount of gas admitted to the interior of the cylinder D is controlled by a rotation of lthis cylinder, and any suitable. means operable from the exterior of' the casF ing maybe'used for this purpose. In the present instance, the cylinder is provided with a radial finger or pin h which projects through a slot 5 formed in the `box E. The latter is provided with a socket H havin a tangential. passagel in which a rod h reciprocates, thls rod being connected to a controlling lever or other suitable device for effecting its reciprocatory movements'. The rod It is provided with a' notch or transverse vsocketwliicli engages a spherical or rounded head on the outer end ofthe finger or pin h, sufficient play being provided between the part h and the rod h as to permit these arts to operatein the respective curved an rectilinear paths. l

Having thus described and ascertainedthe nature of my invention and in what manner the same may be performed, I declare that what I claim is:

1. A carbureter comprising a casing having a tube for the passage of vaporized fuel and primary air, a sup lemental air inlet in alinement with said tu e, and a ,conduit extending laterally from saidv tube, means arranged at the junction of said tube and conduit for deflecting the vaporized fuel and primary air from said tube and the supplemental air from said inlet into said lateral conduit, and a device for controlling in direct proportionv the quantities of vaporized fuel and primary air, and the sup lemental air admitted to said inlet, into sai conduit.

2. A carbureter comprising a casing having a tube for the-mixed fuel and primary air, a su plemental air inlet, and a conduit extending laterally from the casing, a ported jacket separating said conduit from the said tube and sup lemental air inlet, a valve embodying a cylinder having ports arranged to register with those of the jacket, the cylinder being adjustable to vary the area of said ports, and a deflector arranged Within said cylinder for diverting the mixed fuel and primary air andthe sup lemental air through the ports into said con uit. v

3. A carbureter comprising a casing having a box, a tube for conducting mixed fuel and primary air to said box, a valve for admittlng asupply ofsupplemental air to thel box in said Casin a orted jacket mounted in 'said box and aIine axially of said tube, a cylinder rotatable Within said j acket and having ports arranged to register with 'those of the latter,a diaphragm mountedwithin the cylinder and having substantially conical Surfaces at its upper and lower sides for diverting the currents of mixed fuel and prifuel and primary air and the supplemental air into said conduits, a cylinder 'rotatable in said jacket and. having ports arranged to register therewith for controlling the discharge of Huid into said conduits, a deflector mounted within the cylinder for diverting the currents of mixed fuel and air from sai tube and the supplemental air from said inlet into said conduit, and a device o erable from the exterior of the casing foral j usting said cylinder.

In testimony whereof I have hereunto set my hand in presence of two subscribing Witl nesses.` j
